Figure 13 Inserting Flash-Memory SIMMs

Caution

It is normal to feel some resistance, but do not use excessive force on the SIMM, and do

not touch the surface components.

Step 4 Check the alignment of each SIMM to make sure that it is straight and that the alignment

holes are lined up with the plastic socket guides.

If you are ﬁnished replacing SIMMs, continue with the “Replacing the Cover” section on page 21.

Upgrading the ROM

To upgrade the Cisco 3600 series ﬁrmware to a new ROM monitor, you must replace the existing

ROM.

In addition to the tools described in the “Tools and Equipment Needed” section on page 5, you also

need:

• A ROM extraction tool or small ﬂat-blade screwdriver

• Needlenose pliers

Caution Correct placement of the ROM is crucial. If improperly positioned, the new component

could be damaged when the router is powered on. Read all instructions before proceeding. To

prevent damage to the ROM from ESD, follow the ESD procedures described in the “Preventing

Electrostatic Discharge Damage” section on page 5. Be careful not to damage or scratch the printed

circuit card under the ROM.
